Abstract: PROTON-EXCHANGE METHOD OF FORMING OPTICAL WAVEGUIDES Abstract A proton-exchange method of forming optical waveguides within a lithium-based optical substrate is disclosed which utilizes sulfuric acid as theproton source. The substrate is masked to expose the areas desired to be transformed into waveguiding regions and immersed in a heated sulfuric acid bathfor a period of time sufficient to provide the exchange between the protons in the acid and the lithium in the substrate. The presence of the protons in the substrate results in increasing the extraordinary refractive index .DELTA.nc in the unmasked area so that optical guiding may be accomplished. Upon removal of the substrate from the sulfuric acid bath, the substrate must be annealed so as to drive the protons to a depth sufficient to provide effective guiding.

The logic elements process a data bit shifted from the preceding stage with the data bit fedback from the output stage in accordance with the polynomial code for input into the succeeding register stage. The structure further includes means for processing the data bits shifted from a predetermined stage of each shift register structure to provide a keystream; and means for varying the polynomial code of at least one of the shift register structures by applying to the logic elements an enabling polynomial code signal that varies in accordance withthe content of data bits shifted from a predetermined register stage. The polynomial code of one of the shift register structures is not varied in response to the polynomial code signal. The bits that cause the polynomial code signal to bevaried are not included in the keystream.

Abstract: ABSTRACT    A safety enhancing, relatively low-cost, needle cover which is integrally bonded to a disposable needle cannula of a hypodermic syringe and adapted to eliminate the handling and/or destruction of the needle after use.  The needle cover comprises distally and proximally oriented pairs of needle cover segments which are hingedly interconnected and pivotable relative to one another.  The needle cover is collapsible from an open, expanded configuration, with locking fingers thereof engaging and retaining the cannula in an armed state for administering an injection of the fluid contents of the syringe, to a closed, generally planar configuration, with the cannula biased in a shielded state completely surrounded, shielded and isolated after use.  By virtue of the present invention, the needle cannula can be safely discarded within its collapsible cover while avoiding an accidental needle strike and the spread of a contagious, and possibly life threatening disease.

Abstract: A method for treating a body part on or within a living body.  The body part is heated by radiating electromagnetic energy from within the interior of the body part.  The temperature is sensed at a number of spaced locations near the outer periphery of the body part as the energy is radiated.  The heating step is interrupted when the temperature at at least one of the spaced locations near the outer periphery of the body part reaches a particular pre-set value.  The body part is re-heated when the temperature near the one location near the outer periphery of the body part has fallen to a second pre-set value.  This procedure of heating, sensing, interrupting and re-heating is repeated for a pre-determined time.

Abstract: A burner having an air intake at atmospheric pressure, a gas (fuel) supply line and a combustion chamber in which gas from the latter line burns in the presence of atmospheric air drawn in from the intake, is provided with a swingable or rotatable flap-type valve member which controls the volume rate of flow of the air to the combustion site. According to the invention, the position of the valve member is controlled by a parameter generated by the air stream and in response to the pressure in the gas supply line to maintain the air factor (ratio of air to gas) substantially constant. To this end a membrane type pressure detector responds to the pressure in the gas supply line and is connected by a mechanical force transmission mechanism to the flap or other valve element.

Abstract: A submarine optical telecommunications system has two shore based transmitting stations whose signals are combined at a passive, submerged junction. Phase errors are caused by variations in transmission times to the junction. An error signal is generated at the first repeater after the junction. The error signal, which represents the phase errors, is transmitted to a shore station where it is used to adjust the sending phase. A surface acoustic wave filter tuned to half the frequency of the combined signal is the preferred way to generate the error signal.

Depending on sorter size, the number of circular arcs amounts to between two and eight. The eccentricity of the circular arcs relative to their center, based on the rotor axis of rotation, amounts to preferably between 4 and 10 mm. This makes it possible to obtain slight rotor stresses at a good sorting efficacy, preferably also with a mean substance density of more than 3% of fiber suspensions.

Abstract: A transmitting party sends a transfer request to a transfer network. Upon receiving the request, the transfer network allocates a service number (SN) to the transmitting party, if allowed by the current traffic load. The service number identifies the transmitting party for a predetermined period. Upon sending the service number to the communicating party which originated the transfer request, the transfer network preferably starts a timer which monitors the validity period of the service number. The transmitting party sends the destination address (DN) over the transfer network only once during the validity period of the service number. The transfer network associates the destination address (DN) to the service number allocated to the transmitting party. The transmitting party utilizes only the service number (SN) as an identity in the data packets transferred during the actual data transfer, and the transfer network routes the packet to the destination address associated with the service number.

Abstract: ABSTRACT OF THE DISCLOSURE     A character reader includes a digitizer having a tablet on which characters are manually written with a stylus pen.          The digitizer outputs position data on a contact position of the stylus pen with the tablet when the character is written on the tablet.  A non-contact period during which the stylus pen is detached from the tablet is counted in response to the position data supplied thereto from the digitizer.  The non-contact period thus obtained is compared with an identification period and a one character input completion signal is generated when the non-contact period is longer than the identification period.  Movement loci of the stylus pen are obtained based on the position data.  The character is recognized based on the movement loci and the one character input completion signal.  An identification period compensator compensates the identification period so that the identification period is lengthened or shortened as the non-contact period shorter than the identification period among those between the time of detachment of the stylus pen and the time of the subsequent contact is lengthened or shortened respectively after the stylus pen is detached from the tablet and then brought into contact with the tablet again.
